Buzzing when I move the mouse

Sic Puppy · Mar 27, 2008, 05:29 PM

Hi all,
I'm getting a strange buzz/hum whenever I move my mouse across the desktop. I've had the case open and its coming from either the GFX card or in that area on the MB (P5K SE). I've checked he mounting screws and muted things on the volume control ie: Mic, Aux etc but to no avail.

Any ideas,

Cheers
Iain

is your mouse USB? maybe try a different plug?

Sic Puppy · Mar 27, 2008, 05:38 PM

Yeah it is, did try swapping but there was no difference. I have also tried removing all USB devices except the mouse and K/B in case they were drawing too much power, but nothing.

P.S. I'm starting to think this is no sound issue, so possibly in the wrong forum here.

maybe try a different keyboard, could have a stuck key.

i had a keyboard with a broken delete button, would boot and go right to the bios, threw me for a loop for a min before i figured it out.

though it happens when u move the mouse so i dont know

My educated guess: the power supply, or the motherboard. That squealing noise is probably coming from one of the capacitors on the board or the PSU. Do you have another power supply that you can try?

Question: Do you also hear that squealing noise whenever you access data on your hard drive? What I mean is, do you hear this same noise any time you do anything that pulls power from the PSU, like using the optical drive, hard drive, 3D gaming?

Random guesssing time...

Do you get the sound if you turn off your monitor when you move the mouse?

I can certainly hear it when the HDD is being used, can't really hear much during 3D gaming. So whould that mean the PSU is duff?

Try a different mouse and keyboard. If you have a usb mouse and have a PS/2 adapter, try connecting it to the PS/2 port on you motherboard (if you have one for the mouse).

I have a Logitech MX Revolution and was getting noise in the speakers when I moved the mouse.

It's a very good indication, yes. However, everything runs through the board as well as the PSU (mouse is connected to the board which is drawing power from the PSU, but the hard drive is also connected both to the board and the PSU simultaneously). So, to be sure you might want to try isolating the PSU as much as possible in order to verify it's the cause. One way to do this is to remove the PSU from the case, place it beside the case still connected to the system, and boot the system up. That makes it easier to isolate where the sound is coming from since it's not in the case along with everything else.

Ok the noise seems to be coming from the area marked in the photo:

Any ideas?

Thanks Again

Interesting how the noise is coming from the exact area that the USB ports are mounted to on the board. As you can see there are 4 capacitors right behind the USB block on the board, 3 Mosfets, and there is a black square that is actually a cover under which is a coil. All those are power related, and any one of those could make that noise if they are not functioning properly.

BTW, every time you did a test on your mouse you had the keyboard plugged in too, but have you tried testing it with just the mouse plugged in? Also, have you tried using a different keyboard and/or mouse, or using them with a USB to PS2 adapter? If you haven't it might be a good idea, because you need to rule out those devices. If you have tried this, or do try it, and this still happens, then this leads me to think the board is the issue.

I need to point something out here as tough to say with 100% certainty that a component is bad. Here's why: Due to the way the components work there is always a chance that there is a slight flaw in it's construction. However, having flaws doesn't mean it isn't working fine, but rather that it is going to generate a quirk.

On the other hand, it can be a bad thing in so much that it can point to the fact that the components are bad, damaged, or are not working as they should be due to something else in the system (such as a defective keyboard/mouse/PSU).

In any case, it's still good to completely rule certain components out, so I need to reiterate a few things. 1) First thing I would try is a different keyboard/mouse (PS2 and USB) to be sure they aren't causing any feedback. 2) I would then try a new PSU to make sure that it wasn't causing the board to generate feedback. As you can see this would leave the motherboard, and at this point it leaves you with 2 choices: live with the noise hoping it's just quirk, or call Asus and RMA the board for repair just in case the board is actually defective.

On top of what I've suggested trying, if you have a computer shop near you that you can take your system to, it might be worth doing so, and have them try a new power supply, keyboard, or mouse. Most will do so at no cost as the chance you will buy something is there for them if one of those components are defective (although it's best to call ahead to verify that they will help you, for free, before hand). If you have a friend, or another computer that you can borrow these components from to test yours with, even better.

I will try all of these that you have suggested Tipstaff and will report back with any findings. Many thanks for your help so far, it's greatly appreciated.

Not a prob, Iain.

Have you tried by
- setting the mouse sampling rate (can be differently named setting on XP -> Vista ... maybe motion tracking /visibility/etc.) and
- decreasing the hardware acceleration (graphics)?

Also, checking if
- the mouse (or USB controller) is shareing IRQ/Resources w/ audio/graphics adapter and
- if you get rid of the issue by using ASIO or WDM/KS drivers (you can try this fast some audio player as like the NI TRAKTOR BeatPort SYNC by setting it to use ASIO output

If you don't have asio capable sound card there, asio4all driver can be used then. ASIO4ALL - Universal ASIO Driver
When you're on ASIO WDM/KS (Kernel Streaming) mode, you can mute the Wave port showing on Playback control panel (start run... sndvol32.exe (9x - XP, dunno the Vista version).
